Overview
Convert Wire's CRM data model centers on People, Companies, and Deals with custom properties and comprehensive activity tracking. Nutshell uses an analogous People-Company-Leads-Deals structure with a unified pipeline model and integrated email marketing capabilities. We extract Convert Wire data via authenticated API access, performing a complete schema audit to identify all standard fields, custom fields, and association links between records. Each field maps to its Nutshell equivalent or requires custom field creation before migration. Data loads through Nutshell's import API with owner resolution performed by email address matching against your Nutshell user list. The migration carries all standard objects (contacts, companies, deals, activities, notes, attachments) plus any custom fields present in your Convert Wire instance. Workflows, automations, email templates, and reporting configurations require manual rebuild in Nutshell—FlitStack exports complete workflow definitions as reference JSON documents to accelerate that rebuild. A delta-pickup window captures any in-flight changes during the cutover window, and a field-level diff validates the sample migration results before the full run commits, ensuring data integrity throughout the process.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Convert Wire object lands in Nutshell, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Convert Wire
Person / Contact
Nutshell
Person
1:1Convert Wire's Person records map directly to Nutshell People. Email, phone, job title, address fields, and custom properties transfer as-is. Original create and update timestamps are preserved as custom datetime fields since Nutshell sets the system CreatedDate at migration time. This preservation maintains historical reporting continuity and allows teams to track record age in Nutshell after migration.
Convert Wire
Company / Organization
Nutshell
Company
1:1Convert Wire Company records map directly to Nutshell Companies. Standard fields including company name, domain/website, industry classification, employee count, annual revenue, and address information transfer as-is. Any custom fields on Company records also map to Nutshell Company custom fields. Parent-company hierarchies map using Nutshell's parent_company association field, which requires the parent company to exist in Nutshell before the child record migrates. Circular references are flagged and resolved before migration runs.
Convert Wire
Lead / Prospect
Nutshell
Lead
1:1Convert Wire leads (unqualified prospects not yet converted to Person records) map to Nutshell Leads. Lead status, source, score, and custom fields transfer directly. Nutshell Leads have a separate field set from People records—custom field mapping must account for this distinction since a field available on Convert Wire Person may not exist on Nutshell Lead without custom field creation. FlitStack audits the field schema for both record types before migration to ensure all applicable fields transfer correctly.
Convert Wire
Deal / Opportunity
Nutshell
Deal
1:1Convert Wire Deals map to Nutshell Deals with direct field mapping for deal name, amount, stage, probability, expected close date, and owner. Stage names map value-by-value to corresponding Nutshell stage names—FlitStack reviews your Convert Wire stage configuration and creates matching stages in Nutshell before migration. Loss and won statuses align with Nutshell's closed-won/closed-lost model. If your Convert Wire pipeline includes stages not present in Nutshell's default configuration, custom stage creation is required prior to the migration run.
Convert Wire
Pipeline
Nutshell
Pipeline
1:1Nutshell uses a single unified pipeline model for all deals, unlike Convert Wire which may support multiple independent pipelines. If Convert Wire has multiple pipelines, they collapse into one Nutshell pipeline during migration. To preserve visibility into original pipeline origin, FlitStack maps the source pipeline name to a custom text field (Original_Pipeline__c) on each Deal. Teams requiring strict pipeline separation in Nutshell should use tags, custom fields, or separate Nutshell workspaces to simulate pipeline segmentation, which requires planning before migration.
Convert Wire
Activity (Call, Email, Meeting, Task)
Nutshell
Task / Event
1:1Convert Wire activity records (calls, emails, meetings, tasks) map to Nutshell Tasks and Events. Call logs transfer as Tasks with Type='Call'. Meetings transfer as Events with start/end times. Emails map as Tasks with subject and body preserved. Original timestamps and owner assignments carry over.
Convert Wire
Note
Nutshell
Note
1:1Convert Wire notes attach to Person, Company, or Deal records and map directly to Nutshell Notes. Rich-text formatting including bold, italic, lists, and hyperlinks is preserved where the source format is compatible with Nutshell's note format. Notes include the original create datetime and author attribution to maintain complete audit trails in the destination system. If a Convert Wire note contains formatting not supported by Nutshell, FlitStack converts it to plain text with the original content intact.
Convert Wire
Attachment / File
Nutshell
File Attachment
1:1File attachments on Convert Wire records—typically on Deals, Companies, and sometimes People—re-upload to Nutshell's file attachment system via Nutshell's API. Files must be downloaded from Convert Wire's storage and re-hosted in Nutshell's file storage during migration. Nutshell enforces file size limits for attachments, and files exceeding these limits require alternative handling such as linking to external storage. FlitStack identifies files that may exceed size limits before migration so teams can plan accordingly.
Convert Wire
Custom Field (People)
Nutshell
Custom Field (Person)
1:1Convert Wire custom fields on Person records that have no direct Nutshell equivalent require custom field creation in Nutshell before migration begins. FlitStack audits the custom field inventory during the schema review phase and creates all required fields via Nutshell's API. Supported field types include text, number, date, phone, URL, single-select picklist, and multi-select picklist—all of which have Nutshell custom field equivalents. Multi-select fields without a native Nutshell equivalent are serialized as comma-separated text for migration, with native multi-select recreation planned post-migration.
Convert Wire
Custom Field (Company)
Nutshell
Custom Field (Company)
1:1Custom fields on Convert Wire Company records map to Nutshell Company custom fields, following the same creation process as Person custom fields. Multi-select fields use Nutshell's native multi-select type where available for direct mapping. For multi-select fields without a Nutshell equivalent, FlitStack serializes the selected values as comma-separated text in a custom text field, preserving all selected values. Teams requiring true multi-select filtering in Nutshell should plan to recreate these fields as native multi-select post-migration based on the serialized data.
Convert Wire
Custom Field (Deal)
Nutshell
Custom Field (Deal)
1:1Deal-level custom fields in Convert Wire—such as internal order numbers, deal sources, custom probability overrides, and deal-specific tracking fields—map to Nutshell Deal custom fields. FlitStack creates all required Deal custom fields in Nutshell via API during the schema setup phase. Standard field types like text, number, and date map directly, while custom picklists require value mapping between Convert Wire and Nutshell options. All Deal custom fields must exist in Nutshell before the migration run to prevent data loss during the transfer.
Convert Wire
User / Owner
Nutshell
User
1:1Convert Wire user records resolve to Nutshell users by email address match. If a Convert Wire owner has no corresponding Nutshell user, their records assign to a designated fallback user. Unmatched owners are flagged before migration so the team can provision Nutshell accounts first.
Convert Wire
Workflow / Automation
Nutshell
Not Migrated
1:1Workflows, sequences, and automation rules do not transfer. Convert Wire workflow definitions export as JSON documents for manual rebuild in Nutshell's automation builder (available on Pro+ plans). This is a manual step that the FlitStack team coordinates with your Nutshell admin.

Migration approach
Extract Convert Wire data via API access
FlitStack connects to Convert Wire using scoped API credentials with read-only access. We extract all People, Companies, Deals, Leads, Activities, Notes, and custom field values in bulk. API pagination handles large record sets; rate-limit awareness prevents throttling during extraction. The extraction produces a structured JSON dataset organized by object type, preserving all standard fields, custom fields, and association links (person-to-company, deal-to-person).
Build field mapping and validate against Nutshell schema
Our migration engine compares the extracted Convert Wire schema against Nutshell's API schema. We identify direct field matches, value-mapped fields (picklists, enums), and fields requiring custom field creation in Nutshell. Custom fields are created in your Nutshell instance via API before migration runs. We surface any fields with unmapped values or type incompatibilities for your team's decision before the sample migration begins.
Resolve owners and users by email match
Convert Wire owner IDs map to Nutshell users via email address. We run an owner resolution pass against your Nutshell user list. Records with unmatched owners are flagged with a fallback owner assignment (configurable by your team). Owner resolution failures block record migration until resolved—your team can either provision Nutshell accounts for unmatched owners before migration or assign their records to a designated fallback user.
Run sample migration with field-level diff
A representative sample (typically 100–500 records spanning People, Companies, Deals, and Activities) migrates first. We generate a field-level diff comparing source values against destination values for every mapped field. Your team reviews the diff to confirm field mapping accuracy, owner resolution, custom field population, and stage name mapping. No records are deleted or overwritten during the sample—errors surface before the full run commits.
Execute full migration with delta-pickup and rollback
After sample approval, the full migration runs against Nutshell's import API. A delta-pickup window (typically 24–48 hours) captures any records created or modified in Convert Wire during the cutover. An audit log records every operation with source record ID, destination record ID, and timestamp. If reconciliation identifies data discrepancies exceeding your defined threshold, one-click rollback reverts all migrated records and data can be re-mapped before a second attempt.
